This factory-built energy-positive portable classroom provides a high performance, healthy educational environment, while minimizing energy use through careful daylighting and natural ventilation, employing photovoltaic panels to generate substantially more power than consumed. The classroom also serves as an educational tool, with natural forces and systems highlighted, and building performance monitored and broadcast to students inside, as well as to the web. The life-cycle cost is projected lower than previous generation energy-consuming portables.
